I have just purchased this product myself and it is an outstanding oven. It warms up pretty much as soon as you turn it on so be careful. The hobs on the top also stay warm for some time but it helps that a red light appears on the top as well to say it is still warm, especially if you have young children about whilst you are cooking. or if you were to put something on the top make sure the red light has gone off. It cleans easily as well as Im determined not to let grease build up as it can with any oven and grill. An exceptional buy if you are in need of an oven
